BAND-CUTTER AND FEEDER FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No.365,548, dated June 28, 1887.

Application filed June 3, 1886. Serial No. 204,026. (No model.)

To all whom it may concern:

Be it known that I, J OHN HANNIBAL SPUR- GIN, of Carthage, in the county of Jasper and State of Missouri, have invented a new and Improved Band-Gutter and Feeder for Thrashing-Machines, of which the following is a full, clear, and'exact description.

My invention relates to the construction of an improved form of band-cutter and feeder, applicable for use in connection with any of' the invention consists of certain novel constructions and combinations of parts, whereby the general utility of the machine is materially under-almost any conditions that are likely to be met with.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved band-cutter and feeder. Fig. 2 is a plan view of the same. Fig. 3 isa sectional elevation sectional view illustrating the arrangement of the knives by which the bands are cut, the view being takenon line y y of Fig. 3. Fig. 5 is a detail sectional plan view taken on line z z of Fig. 3. Fig. 6 is a view illustrating the mounting of the spreaders, and Fig. 7 is a sectional view taken on broken line w'w of In constructing such a machine as the one illustrated in the drawings above referred to, I provide a main supporting-frame, which consists, essentially, of two sills, 10, that are united by cross-strips 11, and which each carry two vertical posts, 12 and 13, the posts 12, which are higher than the posts 13, being united and braced by a top cross-bar, 14, while the-upper ends of the posts 13 are connected with the posts 12 by means of horizonal strips 16. The rectangular spaces between the posts 12 and 13, the sills 10, and the horizontal bars 16 are closed by suitable side walls, 17. (Shown in Figs. 1 and 3, and indicated by dotted lines supports for a flooring, 18, the arrangement of which is best shown in Figs. 2and. 3.

The main carrier-belts 21 of the machine are mounted on drums 19 and 20, the shafts of said drums being mounted in bearings that are secured to the sills-10. The belts 21 carry cross-strips 2, which are securely attached to each of the belts and extend across the machine just above the floor 18. The drum 19 is merely a guiding-drum, but the drum is a driving-drum, there being a pulley or sprocket-wheel, 22, fixed to one end of its shaft, and this pulley is driven by a belt or chain, 23, that runs in connection with a pul' ley, 24, that is fixed to the main shaft 25. The main shaft 25 extends across the machine beneath the floor 18, and upon its end opposite to that upon which the pulley 24 is fixed there is secured a second pulley or sprocketwheel, 27, over which is passed a belt or chain, 28, which runs over a pulley, 29, that is carried by a shaft, 30, mounted in bearings that are secured to the vertical posts 12. The shaft carries a drum, 31, in the peripheral face of which are formed a number of grooves, 3, the purpose of which will be presently explained. A series of auxiliary belts, 5, for aiding in carrying the grain forward, are arranged upon the drum 31, the lower ends of said belts being guided and supported by a loosely-mounted i of grain passing beneath the said belts, which may be more or less in bulk. The boxes or bearings of the shaft34 are carried by plates 4, one of said plates being arranged on each side of each of the side walls, 17, the plates 4 overlapping each edge of the'slot 35. Upon one end of the shaft 34 there is fixed a pulley or sprocket-wheel, 36, which is rotated through the medium ofa belt or chain, 37, that passes over a pulley, 38, carried by the'shaft 30, as best shown in Fig. 2.

' Between the upper ends of the plates 4 I mountasecond set of boxes, 6, that are formed with upwardly-extending lugs 7, which ride in the grooves 35. Within the boxes 6-is loosely mounted a square shaft, 40, which carries a yoke, 41, that encircles a hub, 44, formed with a cam-groove, 43, in which a pin, 42, carried by the yoke rides, the arrangement being such that as the shaft 34 is revolved a reciprocat ICO ing motion will be imparted to the shaft 40. Upon the shaft 40 is mounted a frame, 45, carrying a number of spreading-tines, 46, the forward ends of which are curved downward, as best shown in Figs. 1 and The shafts 30 and 34 are connected by side strips, 47, and said strips carry a central spacing-block, 48, upon the upper face of which are arranged longitudinal strips 49, the upper ends of which are provided with sockets, the purpose of which will appear farther on.

The knife-carrying attachments 50 each c0nsists of a strip of sheet metal, 51, (see Fig. 4,) that is longitudinally bent upon itself and formed with extending flanges 52, said flanges fitting within guides 53, that are secured to the under face of the spacing-block 48. The knives or sickle-sections 54, which are triangular in shape, are fitted in apertures formed in the strips 51, said apertures, however, being only large enough to permit a portion of each knife to extend. The strips of sheet metal 51, formed as just described, are secured to semicircular hooks 9, which are formed with reduced extensions that fit within the sockets formed in the spacing-strips 49, the bodies of the hooks resting in the grooves 3 of the drum 31. From this construction it will be seen that the knife-carrying attachments 50 may be readily removed from the machine, but that the knives will be held against any downward or forward pressure to which they may happen to be subjected.

In front of the drum 20 is mounted a shaft, 60, carrying spreaders 61, said shaft being mounted in apertures formed in brackets 62, that project downward from the sills 10, the shaft, however, being free to slide within the apertures formed in the brackets; and in order that a rectilinear reciprocating motion may be imparted to the shaft, I secure one of its ends to a yoke, 63, which carries a pin, 64, said yoke encircling a hub, 65, carried by the shaft of the drum 20, while its pin 64 rides in a continuous cam-groove, 66, formed in the peripheral face of the hub, so that when the drum-shaft revolves the spreaders will be reciproeated, as described.

In order that the angle of the spreaders may be adjusted as required, I clamp the shaft and the yoke 03 together by means of a setserew, 66, so that the spreaders 61 may be adjusted to the position shown in full lines in Fig. 6, or to the position shown in dotted lines, or to any intermediate position, or to positions below those in which the spreaders are shown.

The grain to be operated upon is placed in hoppers that are constructed so that they may be readily detached from the main portion of the machine, said hoppers consisting of side leaves, 90, that are hinged to the sills 10, an end piece, 91,- being arranged between the side leaves and provided with eyes 92, which pass through apertures formed in the said leaves, there to be engaged by hooks 93, carried by the side leaves. The hoppers are defined by a central partition, 94, the outer end of which abuts against the end piece, 91, to which it is held by a bolt, 95, which bolt passes through eyes 96, that extend through apertures formed in the end piece, 91. The inner end of the strip 94 is suspended from the cross-beam 14 through the medium of a hanger, 97. Each of the vertical posts 12 carries leaves 98, preferably made of sheet metal, and which are mounted on vertical shafts 99 through the medium of lugs or ears 101, the outer ends of the leaves 98 being curved around, so that they abut against the outer faces of the posts 12; but the leaves are normally held in the position in which they are shown in Fig. 5, which position isindicated by dotted lines in Fig. 3, through the medium of springs 102, which are coiled about the shafts 99, and formed to bear U against the leaves, as clearly indicated. \Vhen the leaves are not required for use, they are moved to the position shown in dotted lines in Fig. 5, and held in this position by means of a button, 104, which is arranged so thatitmay be turned to enter the space between the posts and the outwardly-curved end of the leaf, the said latter end of the leaf being first sprung or pressed outward sufficiently to permit of the reception of the free end of the button between it and the post, thus compressing and holding the springs 102 in such position.

The shaft 25 is driven, when required, by a belt which passes over a pulley, 105, carried by said shaft. The pulley 105 is, however, loosely mounted upon its shaft and is provided with one half of a clutch, 106, the other half of the clutch being formed upon the pulley or sprocket-wheel 24, which, as above stated, is fixed upon the shaft 25, the two parts of the clutch being normally held in engagement by the action of a spring, 107, arranged as best shown in Fig. 2. \Vhen, however, it is desired to stop the machine without disconnecting the belt, the two parts of the clutch 106 are separated by means of a lever, 110, that is pivoted to a bracket, 108, fixed to one of the sills 10, the end of the lever connecting witha yoke, 109, that is secured to that section of the clutch carried by the pulley 105, the lever being thrown in toward the sill in order to disconnect the two parts of the clutch.

In operation, when bound grain is to be fed to the thrashing machine, the bundles are placed in the hoppers upon each side of the central partition, 94, and will be carried forward by the main carrier-belt above the floor 18, the yieldingly-mounted leaves 98 serving to properly guide the bundles and to prevent their clogging in the machine. As the bundles pass beneath the knives 54 the bands will be cut and the frame carrying the auxiliary belts 5 will yield to the bundles as they pass beneath the drum 33. As the grain is carried forward it will be separated and spread by the spreaders 61, which, as before stated. are reciproeated across the path of the grain, and the tines will also act to separate and spread the grain as it is delivered to the th rashing-machine, for, on account of the peculiar formation of the slots 35, the points of the tines will be inclined downward as their upper or butt ends are raised. When loose grain is to be delivered to the thrashing-machine, the central partition, 94, and the knives 54 are removed, and the folding leaves 98 are moved back to the position in which they are shown in dotted lines in Fig. 5, being held in this position. by means of the buttons 104, which buttons are moved so as to enter the spaces between the posts 12and the outwardly-curved ends of the leaves. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a band-cutter and feeder for thrashing machines, the combination, with a rnainearrier-belt and a spacing-block having socketed longitudinal strips applied to its upper surface, of the hooks provided with extensions fitting into the sockets of the longitudinal strips, strips 'of metal secured to said hooks and provided with sicklesorknives and flanges, and guides applied to the under side of the spacingblock and which receive said flanges, substantially as and for the purpose set forth.
